Mic barrel spacer adapter?

[Overlook]

I want to mount a Sennheiser 415 on my HVX200. However, the barrel of the 415 is too small to fill the shock mount of the camera. Is there some kind of spacer/adapter that would allow me to mount the mic? Right now I have just wrapped the mic with gaffer tape so that it fits better.

Thanks.
